DEVICE FOR CONVERTINGYMOTION,

SPECIFICATION formingpart of Letters Patent No. 264,511, dated September 19, 1882.

' Application filed August 24, 1862. (N model.) I

To all whom it may concern:

Be it known that I, JAMES F. BROWN, a citizen of the United States, residing at Ouster Uity, Texas, haveinvented certain new and useful Improvements in Mechanical Movements, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has relation to mechanical 1o movements for converting a reciprocating into a rotary motion so as to impart a steady and regular motion to such machinery as windmills and engines, churning and washing machines, as well as to all other motors to which it may be applied; and the novelty consists in the construction of the same,as will be hereinafter more fully described, and particularly pointed out in the claims.

Figure l is a top plan view of the movement, and Fig. 2 is a detached view of the three cranks shown in their relative position on the shaft.

Ais asolid shaft, provided with journal-bearings a a, which may extend far enough through 2 5 their supports to receive gear wheels or pulleys for imparting motion. This shaft A is provided with sections B B B upon which are turned eccentrics, so as to receive the straps I) 1) b attached to the rods 1, 2, and 3.

O, U, and O are the crank-pins, which also form a portion of the solid shaft A, and each is provided with a connecting-rod, 4, 5, and 6. These crank-pins are placed at equal distances on the revolution, so that when one crank is on the dead-center two are off and exerting their best effect.

7, 8, and 9 represent valve-stems working in the guide-bar D, and- 10, 11, and,12 are the rods which impart the motion, through the connecting-rods, to the crank-shaft A.

It will thus be seen that as long as a reciprocating motion is given the rods 10 11 12 the shaft A will continue to revolve steadily in the direction in which it was first started, and can be as readily started and stopped, as there is no dead-center or point at which the cranks are not in position to respond at once to the prime motor, and the equal distribution of the imparted motion to the shaft A through the medium of the three cranks insures a uniform and regular motioir to the driven machinery.

Having thus described my inveutiomwhatl claim is-- 1. In a device for converting motion, the solid shaft A, having sections B B B form- 5 ing eccentrics, and the crank-pins O, O, and 0', all made of a single piece, substantially as set forth.

2. In a device for converting motion, the shaft A, section's B B B and crank-pins 0, 6c 0', and O in combination with the connecting-rods 10 ll 12 and eccentric-straps I) 1) 11, substantially as set forth.

In testimony whereof I affix my signature, in presence of two witnesses, this 24th day of 6 August, 1882. l

JAMES F. BROWN.
